Welcome to my Java Hash Table tutorial. A Hash Table is a data structure offers fast insertion and searching capabilities. The negative is that they are limited in size because they are based on arrays. They are also hard to order.

People get confused about them because of the Hash Function. A hash function is used to generate a unique key for every item in the array. Since every item is entered using a calculation, this allows you to reverse the calculation to immediately find the proper index. This way you can find items without the need to search through the whole array.

The tutorials are really great and i would expect from you that you come up with more and more tutorials like this on complete Java, J2EE, Frameworks like Spring Hibernate Ant Maven etc. Also if you could creat DVDs of all the topics (and many more), i mentioned above that would be really great and we can purchase them. As i would like to acquire indepth knowledge on Java and related stuffs.

I will definitely cover all of the J2EE topics you mentioned. I just want to get the Android tutorial and C tutorial done first. Thank you for the requests. I’ll always provide my videos for free. I don’t plan on ever selling them.
